Hello everybody,
I am trying to display videos from four cameras. The cameras work perfectly fine but sometimes it displays a blue screen instead of the video. These cameras display videos perfectly when using single through IC Imaging sample utilities. However, one of them always displays blue screen. How do I fix this. The cameras are USB 2.0 Logitech Qucikcam pro 4000 with a PCI card and Video capture card installed.
The platform is Windows XP SP2 with 2002 edition and Pentium 4 3.20 Ghz CPu and 512 MB RAM.

Hello,

If you use four cameras with average videoformats, then the PCI bus bandwidth limits can be achieved very fast. You may should use YUV instead of RGB video formats and slow down the frame rate, if possible.
Also you should use smaller video formats.
